Scottish university research to help developing nations remove arsenic from water supplies

Water supplies across the developing world are often contaminated with arsenic, killing millions. Now a Scottish University has come up with a solar-powered purification plant to remove the arsenic. Clearly solar power enables the plant to operate free of the requirement for local electricity supplies and is, of course, cheap to run.

The technology was developed recently by Professor Bhaskar Sen Gupta, from Heriot-Watt University and will be used first in Bangladesh where one plant will enable a safe supply of water to around 200 schoolchildren. There are plans, of course, to extend the use to other areas.

The plant can reduce the level of arsenic in water from 239 to only 2 micrograms per litre which is well under the World Health Organisation guideline level of no more than 10. Around the world, more than 137 000 000 people are thought to be affected by this problem causing a range of serious health problems including early death.
